' SPECIFICATION forming part of Letters Patent No. 604,006, dated May10, 1898.

Application filed August 14, 1897. Serial No. 648,226. (No model.)

To all whom it may concern: 7

Be it known that I, HENRY C. DUENSING, a citizen of the United States,residing at Beecher, in the county of Will and State of Illinois, haveinvented a new and useful Improvement in Traction-Wheels, of which thefollowing is a specification. My invention relates totraction-wheels,and particularly to means for preventing theaccumulation of snow and ice on the tread of the wheel. Its object is'toprovide a construction in which the tread of a tractionfwheel maybeheated while the wheel is in motion, so as to prevent such accumulation.I attain this object by the mechanism illustrated in theaccompanyingdrawings, in which- Figure 1 is an elevation of a part of atraction-engine embodying my invention, showing part of the boilerand-one of the Wheels with steam connections. Fig. 2 is a verticalsection on the line W W 'of Fig. 1 with the wheeltnrned so that the pipeisin a verti- Fig. 3 is a cross-section of the rim of the wheel, takenon the lineX Xof Fig. 1. Fig. 4 is a vertical section of part of the rimof the wheel, taken on the line Y Y of Fig. 2.

The traction-wheel is provided with a hollow rim formed by fastening anouter rim or casing 2 upon the inner rim 4, leaving the airtightcompartment 1 between same. A gasket 3 extends around the wheel betweenthe two rims on either side, the rims being fas tened together,compressing the gaskets, by

means of the bolts 14. The bolts 14 also serve to secure the rims to thespokes 15'.

The pipe 5, communicating with the compartment 1, is secured to theinner rim 4 and turns with the -wheel,'the lower part of the piperevolving in its connection with the pipe 10. The connection between thepipes 5 and 10 comprises a stuffing-box 7 8. The pipe 5 is provided withports 6, communicating with the pipe 10. The outer end of the pipe 5 isclosed by a cap 9. I The pipe l0 communicateswith the boiler 11 and isprovided with a cock 17 for controlling such communication.

The compartment 1 in the rim has therein a partition 13, near the pipe5. On the side of the partition away from the pipe 5 a' cock 12 isprovided for discharging the exhaust.

The pipes 5 and 10 are removably secured other side of the partition,where same conil denses' and where the exhaust maybe dis- 7 chargedthrough the cook 12. v

The advantages of my device will also be readily understood. Heretoforemuch difliculty has been experienced with traction-en gines through theformation of ice on the tread of the wheel, especially Where the treadis provided with projection 18,, the ice either forming large lumps orforming a smooth sur face between the projections, and thus materiallyinterfering with the movement and power of the wheel. this objection bypreventing the formation of ice while the engine is in operation andalso providing" convenient means for removing ice which may form uponthe engine while same is not in use.

It will be seen that the details of construction may be considerablyaltered without departing from the spirit of my invention.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. A traction-wheel having a hollow airtight rim, with a partition 13therein, and a discharge-cock on one side of said partition opening outof the rim, in combination with steam connections communicating withsaid rim on the opposite side of the partition, and adapted to conveysteam orhot air into said My device overcomes rim. while the wheel is inmotion, for the purposes specified. I

2. A traction wheel having a hollow airtight rim; in combination with apipe 5 communicating therewith at one end, having its other end bent inline with the axle of the wheel, and having a port 6 therein; anairtight connection in which said other end is journaled; and a pipe 10secured to said connection for conveying steam or hot air through theport 6 and into said rim, for the purposes specified.

3. :A traction rwheel having a hollow, airtight rim with a partition 13therein, and a discharge-cock on one side of said partition its otherend bent in line with the axle of the wheel and having a port 6 therein;an air-' tight connection in which said other end is journaled; and apipe 10 secured to said connection for conveyin g steam or hot airthrough v the port 6 and into said riin, for the purposes specified.

4. A traction-Wheel having an inner rim 4 and an outer rim 2 secured tosame and. grooved so as to form an air-tight compart-- ment between saidrims, and a gasket 3 interf vening said rims on either side, incombination with steam connections, adapted to convvey steam or hot airinto said compartment while the wheel is in motion, substantially as 20and for the purposes specified.
